PRESSURIZING SYSTEM FOR CRYOGENIC PRESSURE VESSEL

摘要

The present invention relates to a pressurizing system for a cryogenic pressure vessel. A pressurizing system for a cryogenic pressure vessel according to the present invention includes a pressure vessel which accommodates a coolant and a superconducting fault current limiter and maintains the supper conduction state of the superconducting fault current limiter; a pressing part which supplies a gas into the pressure vessel, increases a pressure while it is in a normal state of maintaining a supper-cooling state of the coolant, and stops the supply of the gas when it reaches the normal state; and a supper-cooling maintaining part which cools some of coolant discharged from the pressure vessel, circulates it along the pressure vessel, evaporates the rest, and resupplies it to the pressure vessel. Therefore, at only an initial pressure, the cryogenic pressure vessel using the pressuring part is pressurized to the normal state. After it reaches the normal state, the pressure state of the cryogenic pressure vessel is maintained by the supper-cooling maintaining part. Therefore, the consumption of energy can be minimized.
